Working Principle

The ISL78213ARZ-T of Intersil is a two-phase DC/DC step down converter with integrated MOSFETs and activated terminals. The device operates by using an advanced proprietary control loop to ensure fast transient response as corner frequency of input voltage and output current. The ISL78213ARZ-T also has internal compensation components and pre-bias startup. Therefore, it is ideal for point of load (POL) applications and maintains excellent line, load and temperature stability. Furthermore, the device has undervoltage lock-out (UVLO), temperature shutdown, current limit, over temperature protection (OTP) and over-voltage protection (OVP). These are provided to protect the device from overloading due to faulty conditions.

The ISL78213ARZ-T also integrates a low-side drive power MOSFET and a synchronous high side drive power MOSFET which are connected in phase two topology, providing efficient operation and high reliability. In the phase two topology, the low-side and the high-side power MOSFETs switch in an alternating fashion, helping to minimize switching losses. Therefore, this voltage regulator is highly efficient and suitable for high voltage, high-current and low-profile applications.
